Regexcellent

About this product

Learn regular expressions by writing them. Regexcellent combines 40 interactive lessons across eight modules with a live playground, match highlighting, capture details, token explanations and saved patterns. Practice with regex golf and a daily rotating challenge, or look up tokens in the reference. Export supported Swift, Kotlin, JavaScript and Python snippets with engine-difference warnings. Learning works offline without an account. Every feature is free; optional tips unlock nothing.
